oscars and Green Terror

Hey,

thanks... The 2 filters you recommended are both "hang-on" types...

why would someone choose that style over a camister ?

just asking cuz i am new and dont know....

please explain.
 
HOB filters are generally cheaper and simpler, so you can get better filtering on a budget. More bang for the buck.

But personally I don't think there is a problem with your current Eheim, it should support any sensible number of fish that you could keep in that tank.

But I agree with the others, that as adults, you will have too many fish, and extra filtering isn't going to be enough to make up for that.

Right now you don't have a problem as the fish are only babies. Next year when they start to mature.. not so good. Aggression, problems with water quality etc. So there is no need to panic, but you do need to plan ahead.

Remember we are planning on you keeping BIG healthy fish that might live for 10 years or more, not just keeping them alive till next year.

I'm planning to move my Oscar and Pleco to an 85gal soon, and I can only get away with that because the pleco is a rescue and a little stunted, like 12" after 10 years, so is not growing much more. But thats just 2 fish, and the tank will be fully stocked.

ok thanks for the help... i got rid of the feeders...well almost all of them... i cant catch 6 of them! :) im sure the oscar of get to them sooner or later anyways.

I will also get rid of the plecos, when i can catch them also...they are small and hide alot.

I will look into getting an additional filter in 6-8 moths then, as they get larger, and I see that the water is going south faster then before.
 
i'd be getting that extra filter now. oscars grow fast. mine isn't 2 years old yet and is pushing 11 inches. in the first 6 months of an oscar's life, they do the most growing, at least an inch per month if they are cared for properly.
 
ok, so what im thinking is that i can get the hang on type, and clean more often than the cannister? but will it really matter if i just wash it out with little concern for the bacteria in it, as the canister already has the bacteria culture? or are they both important?
 
keep your bacteria count up and good in both filters. with messy fish like O's you want as much bacteria as possible in case there should be an ammonia spike. rinse the media from both filters in old tank water.
 
Hang on back filters will help with the mechanical filtration in a tank with large fish.Plus they will help with the biological filtration as well. If you ever find the need to use chemical filtration,it is easier to add to them.

If a HOB does not interest you,a Magnum 350 canister would be a good filter to add to your system. You can add the micron cartridge for water polishing,which may be something you want when keeping larger fish.
